BRACKET AND BEARING FOR SHAFTING AND SHAFTS.

SPECIFICATION forming-part of Letters Patent No. 231,866, dated August31, 1880.

7 Application filed July 29, 1880. (No model.) Patented in EnglandFebruary 16, 1880.

To all whom it may concern:

Be it known that we, J osnPH SAMUEL TAY- LOR and STEPHEN WILLIAMUHALLEN, of the Derwent Foundry, Birmingham, in the county of Warwick,in that part of the United Kingdom called England, engineers, havejointly invented an Improved Combination Shaft- Bracket, with hearingadjustable and self-adjusting, applicable as hangers and wall-brackets,pedestals, and bearing-blocks, and designed for carrying line, single,and other rotating shafting or shafts, (for which we have obtained apatent in Great Britain, No. 670', bearing date February 16, 1880,) ofwhich the following is a specification.

The nature ofour iiwention, relating to the construction of brackets andbearingsfor line and other rotating shafting and shafts, consists intheir capability of adjustment, after the sole or foot plates of suchbrackets have respectively been permanently fixed in a line orotherwise, without much regard to precision,

, either to the side or under side of beams or of floors in the positionof hangers, to walls, pillars, or columns as projecting brackets, uponfloors as pedestals, and in other positions and places, the bearings ofsuch brackets having sometimes formed within them, in the usual way, acavity to contain a liquid lubricant, which, by well-known means, issupplied to the frictional surfaces both mechanically and by capillaryattraction.

Our object is to provide, in combination with such brackets, ashaft-bearin g, either furnished with soft-metal coupled linings andself-lubricating when required, or a plain bored bearing the true linealarrangement whereof does .not so much depend as heretofore upon theaccuracy with which the sole or foot plate of the bracket is permanentlyfixed to or uponits seat or bed. The necessary adjustment beingafterward accomplished by the adjustability of the bearing, we areenabled to save nearly all the expense for skilled labor and valuabletime of the workmen which the tedious operation of fixing, leveling, andsetting in the ordinary manner line and other shafting always entails.The true lineal position of a series of our bearings is with the utmostprecision capable of being regulated subsequently by adj usting-screws,assisted by a tendency in each bearing to adj ustor bed itself to thetrue axial line of the shaft; and, whatis very important, afteradjustment the parts of the bracket are, by means of cram ping-bolts, sosecured in their adjusted position as to be made quite as immovable andrigid as they would be if the separate parts of the bracket and bearingwere all cast in one piece.

Some of the many advantages derivable from the use of ourcombination-bracket bearing embrace the expeditious fixing of thefootplates of the bracket base-piece, which, as no special exactness isrequired, is very quickly accomplished, and consequently the saving inthe cost of skilled labor is very considerable, besides the avoidance ofall slack belts or necessity forthe use of packing; also, auniformpressure always existing between that portion of the shaft which restson thebearingthroughout the lengthof the latter in consequence of itsability to adjust itself results in less wear, less oil consumed, andsmooth running with less power, particularly in the case of thosebearings 'which are provided with a self-lubrt eating appliance.

Another great advantage consists in being able at any future time,without disturbing any of the base-plates or the screws whereby they areheld, to readjust the level or lineal truth of a shaft or a line ofshaftin g if,-in consequence of the subsidence of foundations, theoverloading of floors, or from othercauses, it has suffered derangement.

Oiir invention may be advantageously employed in all mills, factories,workshops, and places where line-shafting and single orother shafts,whether horizontal, vertical, or diagonal, are required; also, wherepoweris used in mining and engineering operations, for contractors workgenerally, and in all cases where the frequent shifting q fbracket-beds, blocks,'and beams is indispensable and new adjustments areconstantly required, according to the rate of progress of the work.

Our new combination bracket and bearing consists of three principalparts-win, the base or bracket piece, which carries the foot or soleplate the bearing proper, which receives and supports the shaft theadjustable extension swiveling piece, which is interposed and connectedat one end to the bracket base-piece and at the other end to thebearing. These parts, in collective relation to each other, are capableof being adjusted by two suitable or special adjusting-screws, and bymeans of cramping-bolts subsequently they can be fixed in a variety ofpositions, respectively suited to carry either horizontal, vertical, ordiagonal shafting, although the foot or sole plates of the brackets befixed, as may be most convenient, either to an overhead beam, thesurface of awall, to a pillar or column, or upon afioor, and it is thisgeneral power of adaptation, in addition to its many other advantages,that we believe gives to our invention a pre-eniinence that will soonbecome established.

We will now proceed, in the first place, to describe and show theconstruction of our adjustable combination bracket-bearing according toour primary arrangement and contiguration of the several parts. In thesecond place we will describe and show divers arrangement-s of ourbracket-bearing wherein, respectively, one or more of the parts aremodified in configuration, the adjusting'screws in some cases being alsomodified in form and variously applied; and, in the third place, we willdescribe and show some of the various positions and adaptations to whichour invention can be advantageously applied. In each case we makereference to the one or other of the figures on the drawings heretoannexed, and the letters and digits used in our description todistinguish the several parts and details will be found to agree withthe letters and digits marked on the corresponding parts and details, asshown on the drawings by the several figures thereon-that is to say,referring to Sheets Nos. 1., 2, and 3:

The primary arrangement of our bracketbearing is exhibited on Sheet 1,Figure 1 being a front view of the several parts in combination; Fig. 2,a side view of the bracket atfixed to a wall; and Fig. 3 is a plan viewof the same.

The sole or foot plate A of the bracket basepie'ce A is, as usual,furnished with holes for the reception of the bolts employed to afiix itfirmly to beams, walls, pillars, or floors,.it be ing shown in this caseas a bracket affixed to a wall. Two strong curved spurs, forming a partof the bracket base-piece A, are cast upon the upper surface of thesole-plate A. They spring from the face of the plate, respectively, ator about a right angle near the ends, and, thence inclining one towardthe other in the form of an arch, meet exactly over the center of thebase-plate. The free or meeting end of each spur has the form internallyof a semicircular groove, so that the two ends (which do not unite) formacramping coupling, (marked A and each is laterally furnished externallywith A which marks two projecting lugs that have holes for the receptionof two cramping-bolts, (marked A This coupling in our best brackets isvertically bored out to receive the straight end (marked B) of theadjustable extension swivel-piece B, which end is turned and finished toa corresponding size, so as to be capable of rotating and slidingendwise in the coupling The extension-piece B forms the adjustableconnection between the bracket base-piece A and the adjustable part A,that carries 0, which marks the shaft-bearing. That portion whichadjoins the straight end of theextension-piece B is suddenly bent orcrankedto a right .angle, and thence it takes the shape more or less ofa quadrant. On its extreme outer end it has (cast in one piece with it)a split boss, (marked 13 which boss carries B that marks two lugs, onelug being placed on one side and the other on the opposite side of thesplit part of the boss, and both have corresponding holes to receive acramping-bolt, (marked 15*.) A small projecting bracket, B is also caston theouter end of the extensionpiece to carry one end of D, which marksthe screw that adjusts the projecting shank O of the bearing proper, O.The shank O of the bearing of our best brackets is also latheturned tosuit the internal size of the split boss B which is so placed on theextension-piece and bored out that its axial line intersects at a rightangle the axial line of its straight end B. The shaft-bearing proper, O,is, by preference ,castiu one piece with its shank O, and at an angletherewith of about forty-five degrees.

0 marks the metallic linings of the bearing; G the cap; 0, thecap-screws, and 0 oilpassages.

111 E1 4, D marks the adjusting-screw that regulates the longitudinalposition of the straightendot the extension-piece inthecramping-coupling A of the bracket base-piece. The lower end of thisscrew is seen to be firmly confined in a hole made in the center throughthe sole-plate A, but it has liberty to rotate. The other end of thescrew is screw-threaded and furnished with a lock-nut. [t is screwedinto a threaded hole concentrically made in the straight end of theextension-piece, and, according to the direction in which the screw isturned, will draw the-extension-pieee either up or down, or inward andoutward, as may be required to effect (in the case of a wallbracket) thelateral adjustment of the bearin g G, the vertical adjustment whereof isefl'ected by the screw E, Fig. 5, the plain endot' which is firmlysecured, with liberty to turn, in a hole made through the smallbracket-piece B in the direction of the end of the bearingshank O, inwhich there is a threaded hole made to receive the opposite end of thescrew E, which is screw-threaded to correspond, and by this means theshank of the bearing is moved endwise in either direction, and thevertical or leveling adjustment of the bearing is thereby effected.When, however, our combinatioirbracket is fixed to the under side of anoverhead beam, the vertical or leveling adjustment is efi'ected by thescrew D, which then moves the extension-piece either up or down, and thelateral adjustment is then effected by the screw E. After the linealadjustment of the line ofshaftin g is complete and the several bearingshave separately bedded themselves to the shaft, the nuts on thecramping-bolts of the coupling A and of the split boss B respectively,are thoroughly tightened up, so as to cause the cramping-eouplin g togripe the end B of the extensionhese and 'the split boss to gripe theshank of the hearing so forcibly that the whole of the parts combinedare im movabl y secured in their adjusted position, and so that they areheld as rigidly-as if they consisted only of one piece.

Knowing, however, that constant dropping will wear away stone, so webelieve that the constantjarring and rattling of tooth-wheels might intime alter the adjustment. We therefore, as an additional security inthe case of those brackets that are placed contiguous to tooth-gearing,pass steel dowels or keys or steady-screws through the parts held by thee amping-bolts.

The several details and parts of our combination-bracket bearing areshown separately on Sheet 1 by the following figures, viz:

Figs. 6 and 7 exhibit, respectively, a plan and a front view of A, whichmarks the bracket base-piece, A being the sole or foot plate, A thecrampirig-coupling, and A the lugs for the cran'iping-bolts.

Figs. 8 and 9 show, respectively, a side view and an end view of B, theextension swivelpiece, B marking the straight end, B the split boss,Bthe cram 'iing-lugs,and B the small bracket-piece.

Figs. 10 and 11 respectively show a side view and a plan of our bracloatbearing O, the body of which is made in one casting with O, which marksthe shank; G the metallic linings; (3 the cap; the holes for cap-screws,and oil-passages.

Figs. l2, l3, and 14 exhibit, respectively, a side view, an underneathview, and an end view of our bracket-bearing adapted as a hanger,secured to the under surface of an overhead beam, and arranged forcarrying one end of a counter-shaft, thestrap-guide support beingattached to the bracket-bearing. This bracket is the same in mostrespects as that already described with reference to Figs. 1, 2, and 3,excepting that no adjusting-screws are employed. A (as before) marks thebracket basepiece, which is the same in form with sole-plate A and'eramping-coupling A As before, B marks the extension swivel-piece,B itsstraight end, and B the split boss, the small bracketpiece beingdispensed with. 0 marks the shafthearing, which in this bracket is shownto be a plain bored-out boss cast with a shank, (J. The annular clip Fis fastened on one end of the bearing by means of a screwbolt, F. Theouter end of F which marks the projecting arm of the clip, has the formof a chain-link, made so to receive F which marks a small pulley, theaxle whereof, F finds a bearing in two plain holes, made respectivelycoincident in the opposite sides of the link-formed end of the clip, thepulley filling up the space between. A certain length at the end of theaxle is screw-threaded externally,'and the hole through the center ofthe pulley is screwthreaded to correspond. The periphery of the pulleyis formed with recesses to receive an endless chain, (marked F whichchain hangs from the pulley in the form of a long loop. \Vhen the chainis pulled on either side it causes the pulley to rotate, and the pulley.being confined between the sides of the linkformed end of the arm of theclip, by means of its internal screw, effects the nccessarylongitudinalmovement of the axle to which the bar which carries the strap'guides Fis welded.

Figs. 15 and 16 respectively show aside view and an end view of theplain shaft-bearing O, with its shank U; and Figs. 17 and 18 show twoviews of the extension-piece B minus the small bracket-piece.

Figs. 19 and 20 represent, respectively, a transverse section and alongitudinal section of one of our best-class 'shaft'bearings, 0, castwith a shank, 0, showing the shaft 0 the oilcavity P, and the endlesscottoirwick feeder Q. This mode of self-lubrication, however, forms nopart of our present invention, and all the novelty we shall hereinafterclaim in respect thereof consists in casting in one piece or conjoiningthe body-piece of a self-lubricating shaft-bearing with or to anadjustable shank.

It will now be seen that we make the shaftbearings of our combinationadjustable brackets (in order to meet all requirements) sometimescylindrical, orofsolid metal, being simply bored out to the size of theshaft, (as described with reference to'Figs. l2 and 15;) but generallywe furnish them internally with bronze or with bell-metal coupledlinings, or with metalline plugs, or otherwise mount them according toany or all of the numerous ways known and practiced by mechanics and byengineers, the size and strength of the bracket and parts, the style ofthe bearing employed, and the manner of fitting it being more or lessdependent upon the nature, weight, and intended speed of the rotatingshaft and the limit by which we are compelled to regulate the cost.

Figs. 21 and 22 represent two views of a bracket-piece designed forattachment to the side of a beam, and Figs. 23 and 24 two views ofanother form of bracket-piece designed for attachment to the under sideof a beam; Both of these bracket-pieces are furnished with our splitbosses B for holding and cramping the adjustable end B of theextension-piece B, or, when the latter (for want of room or from anyother cause) is omitted, the shank of the bearing 0, such forms ofbracket-pieces being used occasionally when a line-shaft runs closebeneath or alongside a beam but in case where a shaft or a portion ofline of shafting runs a considerable distance from a beam to which wedesire to aflix a bracket, we employ a long bracket-piece, such as isshown by Figs. 25 and 26, which respectively represent a side and anedge view. This bracket-piece, it will be seen, is also furnished withour split boss B wherein the straight end of an extension-piece, whenthe bracket is fixed, may be inserted either at the upper or the underside of the split boss, and by this means any reasonable distance orposition of the shaft may be reached.

Sheets 4, 5, and 6: On these sheets of drawings we show, by one or moreof the different figures thereon, the several modifications hereinbeforementioned as relating chiefly to changes in the configuration of two ofthe principal parts-viz., the bracket-piece A and the adjustableextension swiveling piece B-the bearings 0 being (with one exception) inall the other modifications furnished with an adjustable shank.

Figs. 1 and 2 show, in a modified form, one of our combinationbracket-bearings adapted as a hanger depending from a beam. In thismodification the bracket base-piece is solid, and, as usual, isfurnished with a sole-plate, A, and two projecting lugs, (marked A onebeing cast at each side of its outer end, A which is made hollow like ahalf-bearing to receive and form a bed for the adjustable portion B ofthe U-formed extension-piece B, which (see Fi 2) is held in its place byG, that marks a staple-formed cramping-bolt screwthreaded and furnishedwith a nut at each end. The extension-piece of this bracket is providedwith a split boss, B to receive the shank G of thebearing O, which ismounted with coupled linings and capped, the cap and the linings beingrespectively held in place by one hook-headed bolt, (marked H,) theother end of this bolt being screw-threaded and furnished with a nut fortightening up. The cap 0 is provided with a transverse recess to receivethe hooked head of the bolt H, by which means the cap is kept inposition endwise, and, for a similar purpose, the ends of the liningsrespectively are provided with small projecting nibs, (see Fig. 1,)

that prevent them slidin g endwise or turning with the shaft. The twoadjustments of this braeket-viz., of the extension-piece and of theshank of the bearing, respectively-are made by means of duplexadjusting-screws, (marked J both ends of which screws are screw-threadedand provided with nuts. These duplex screws carry, laterally projectingat their mid-length, a small square nib, J, that is designed forentering an annular recess, J formed in the adjustable part of theextension-piece. The duplex adjusting-screws are disposed in groovedrecesses formed, as shown, 1n the solid or the stationary parts,respectively, of the bracket basepiece and the split boss of theextension-piece, but so contiguous to the parts to be adjusted (see Fig.15) that the projecting nibs of the screws enter the annular recesses,respectively, of the said parts. These duplex screws may be usedin anyof the modifications hereinafter to be described, and also in thebrackets already described, and exhibited on Sheets 1, 2, and 3.

After adjustment the parts are maintained in permanent position-viz.,the extensionpiece adjustment, which, in this case, is horizontal-by thethorough tightening up of the nuts on the ends of the staple-formedcrampin g-bolt G, and the shank of the hearing by the cramping-bolt ofthe split boss B on the extension-piece. Figs. 4 and 5 show thehalf-bearing of the base-piece of this bracket placed in a differentposition to that shown in Figs. 1 and 2, and which, in some cases, ispreferable.

Figs. 6, 7, and 8 show three separate views of the extension-piece ofthis bracket in its modified form and furnished with a split boss havinglugs and a cramping-bolt.

Figs. 9 and 10 represent the second modification of our bracket-bearing,the parts A and B being further changed in configuration, but' similarlyarranged.

On referring to the drawings it will be seen that the bracket base-pieceA is a solid block cast on the sole-plate A, by which it is affixed toan overhead beam, as shown, but may be disposed otherwise. It carries asplit boss placed horizontally, and is furnished with lugs forcramping-bolts, the whole being cast in one piece.

The extension-piece B of this modification will be seen to have anotherform that enables its adjustable end B to enter horizontally the splitboss B of the bracket base-piece, so as to bring the center of the splitboss which it carries coincident at a right angle with-the axial line ofits adjustable end. A plain boredout bearing, 0, with shank verticallydisposed, is shown combined in this modification; but it will beunderstood with regard to this, as in most of the other modifications,that any of the shank-bearings that have been or have to be describedmay be adapted thereto. The adjustments in this bracket-bearingareeffected by two of the duplex adjusting-screws already described withreference to Figs. 3 and 15.

Figs. l1, l2, and 13 represent three views of a -formed extension-pieceB, made in two parts, fixed together by a bolt that is seen to passlengthwise through the adjustable part, and by this means anextension-piece of this form may be employed either with acramping-coupling or a split boss. The two free ends form acramping-coupling to receive and secure the shank of a bearing afteradjustment, for which latter purpose a duplex screw, J, is shown.

Figs. l4, l5, and 16 represent our third modification, which ispresented as a hanging bracket, the base-piece A of which has the formof a truncated tube, one end whereof is centrally cast to its sole-plateA, and at a right angle projects therefrom, an annular recess beingformed round the tube to receive the nib J of a duplex adjusting screw,J. Formed on each of the ends, respectively, of the extension-piece ofthis modification there is a kind of half-bearin g, marked,respectively,

A and A the former being adapted to one side of the truncated tube orbase-pieceA and the latter to the shank of the bearing, the body part ofthe extension-piece B being so quadrantally curved that the halfbearings stand relatively one ataright angle to the other, and both ofthem are furnished with two lugs, onelug on each side, and bored for thereception of the screwed ends of staple-form ed crampingbolts G, therebeing two of these bolts to each. By means of these half-bearings andcramping-bolts the parts of the bracket are held in position duringadjustment, which, as shown in the drawings, is effected by two duplexadjusting-screws respeetivelydisposedin grooves in the half-bearin gs,and made therein for their reception. The bearing of this bracket may beeither one of our best lined or one of the simplest and cheapest kind,as shown in the drawings; but whichever is used its shank must have anannular groove made round it to receive the nib of the duplexadjusting-screw.

After the adjustment is complete the nuts on the end of thestaple-formed cramping-bolts, respectively, are thoroughly tightened up,and bymeans of this powerful gripe the parts of the bracket areimmovably fixed in the adjusted position.

Fig. 17 shows a simple contrivance for ad- 0 jnsting the round end ofthe extension-piecein the clamping coupling of an arch -formedbracket-piece. Fixed crosswise on the end of the extension-piece B is asmall carrier, K, having one end projecting, which end has ascrew-threaded hole made through it to receive the adjusting-screw K,the end whereof rests on the end of the clam pin g-coupling. By turningthe screw either to the right or to the left the extension-piece iscaused or is free to slide either upward or downward in the coupling,and by this means its adjustment is efiected.

Fig. 18 exhibits another mode for adjusting the end of theextension-piece in a clampingcoupling. In this case it is accomplishedby means of a long screw-threaded bolt, (marked L,) the T-formed endwhereof isshown fixed to the sole plate of an arch formed bracketbase-piece. The fixed bolt, projecting thence at a right angle, passesconcentrically through the cra-mpin g-couplin g A A clearing-hole toreceive the bolt is drilled or made lengthwise completely through thestraight end of the extension-piece. The extreme end of the bolt issuingat that part of the extension-piece where i t is suddenly bent isprovided with a nut, and

there is another nut placed on the bolt near its fixed end. Theserewbolt being immovable, it will be seen that the adjustment iseffected by the nuts.

Figs. 19 and 20 show, respectively, a side view and a section of ahanging bracket similar to that already described with reference to Fig.12 on Sheet 2, excepting that a split boss, 13, is seen to take theplace of the crampingcoupling, and a duplex adjusting-screw is adaptedto the split boss for the purpose of effecting the vertical adjustmentof the extension-piece.

Fig. 21 represents our fourth modification adapted as a hanging bracketto abeam. The base-piece A of this bracket comprises a round truncatedtubular piece cast projecting from the sole-plate and having atriangular support on each side. The body of the extensionpiece 13 hasthe form of a quadrant, and at both ends it is furnished with a splitboss, B respectively disposed on the same plane, and relatively standingone at aright angle to the other. These split bosses are, as usual,fitted with cramping-bolts, and when making up or combining the parts ofthe bracket one of the split bosses is slid on the tubular part of thebracket-base, and in the other is inserted the shank of the bearing 0.In this modification no adjusting-screws are shown; but when requiredthose of the duplex kind are preferable.

Fig. 22 exhibits a dwarf bracket base-piece applied as a hanger to theunder side of a beam, and consisting of a split boss furnished with lugsand a cramping-bolt and cast upon a soleplate. The straight end of anextension-piece is shown in the split boss. Such a bracket base-piece asthis at times is found to be very useful in places where, for want ofspace, one of the larger kind cannot be used.

Figs. 23 and 24 exhibit, respectively, a side view and an end view ofthe fifth modification of our bracket-bearing fixed as a hanger to anoverhead beam. The base-piece Aof this bracket will be seen to consistofa truncated tube centrally projecting from its sole-plate at a rightangle, and having an adjustable split boss fixed by a cramping-bolt onits outer end, which is reduced to the required size. The plate of theextension-piece B is affixed to the back of the boss by two screws,which pass through slotted holes made in the plate and are screwed intothreaded holes made for their reception in the back of the split boss.Also, cast upon the outer end of the extension-piece is a split bosswith lugs and furnished with a cramping-bolt for fixing in this boss theshank of the bearing 0. The vertical adjustment of the extension-pieceis effected by the screw M, and the cramping-bolts, when screwed up,make the parts relatively immovable.

Figs. 25 and 26 exhibit, respectively, a side view and an end view of anadjustable swiveling bracket and bearing, the sole-plate A of thebracket-base A being affixed to a wall. The base of this bracket has theform of acircular' hub, andlthe two adjusting-screws, N i

and N as adapted to the extension-piece B, have along with the latterliberty to rotate on the central screw, N, for the purpose of adjustmentor for bringing the bearing 0 (which is one of the ordinary kind) intosuitable position for receiving the shaft. After adjustment theextension-piece is finally fixed to the base-piece by tightening up thescrew N The projecting part of the extension-piece 1?, which is shown insection by Fig. 27 and in plan by Fig. 28, carries a plain coupledhearing, the cap part whereof being separated at an angle of aboutforty-five degrees. The position of the bearing is adjusted laterally bythe screw N and it is afterward fixed by the screw N Figs. 29 and 30represent, respectively, afront view and a section of one of ourcombinationbrackets in a modified form, so far as regards the base-pieceA. which is dwarfed for the purpose of adapting the bracket to awall-box, the base-piece consisting of a split boss cast upon asole-plate similar to that described with refe ence' to Fig. 22. Thestraight end of the extension-piece B is correspondingly shortened, andthe round shank of a plain coupled hearing is shown'fixed in a splitboss, B that is east on its upper end. In the above figures noadjusting-screws are shown.

Figs. 31, 32, and 33 exhibit, respectively, an end view, a side view,and a top view of a bracket affixed as a hanger to the side of a beam,the bracket base-piece A carrying a split boss, B for receiving andfinally securing the end of the extension-piece B, which is so arrangedthat, as shown in the drawings, the bearing can be brought into aposition suited to receive a vertical shaft, the novelty in this bracketbeing chiefly confined to the configuration of the base-piece incombination with a split boss.

Figs. 34 and 35 represent, respectively, .the

plan and side view of a bracket having its soleplate fastened to a wall.The base-piece A of this bracket is modified in form, while the otherparts-via, the screws for adjusting, the extension-piece B and thebearin g O-are in all respects the same as previously described withreference to Figs. 1, 2, and 3 on Sheet 1. Instead, however, of castingtwo curved spurs upon the sole-plate to form the basepiece and thecramping-coupling, as previously shown and described, it will be seenthat the foot-plate A has only one spur cast thereon but the substanceof this spur is so increased that it possesses strength sufficient tocarry all the combined parts ofthe bracket and bearin g besides it iscapable of being furnished with a split boss, B having the necessarylugs and a cramping-bolt for receiving and rigidly securin g the end ofthe extension-piece after its final adjustment.

Figs. 36 and 37 exhibit, respectively, the side view of a bracketsecured to a wall and a view of its base-piece. This bracket is, in allrespects, the same as that described and shown by Fig. 21, whichexhibits a hanger affixed to a beam, excepting that the bearin g iscoupled. It is therefore unnecessary to repeat the description here.

Figs. 38 and 39 represent, respectively, an elevation and a plan of abracket having the sole-plate A of its base-piece affixed as a pedestalto a floor. Its novelty consists in the peculiar construction of itsbase-piece A, which is a modification of the arch-formed class, having acramping-coupling, as described in our primary arrangement. (Shown byFigs. 1, 2, and 3, Sheet 1.) The two segments or side spurs of the arch,it will be seen in Fig. 38, vary in substance, that marked A beinginflexible and so much stronger than the other that it is capable ofsupporting the whole weight and strain of the bracket. The other spur, Ais intentionally made weaker, and consequently lighter, in order that itmay more readily yield when the bolts of the crampingeoupling A aretightened up to secure the end B of the extension'piece 13, our objectin this arrangement being the avoidance of all reaction against thecramping-bolts when finally tightened up, and which we effect in ourarchshaped bracket base-pieces by modifying their construction, as abovedescribed.

Figs. 40 and 41 exhibit, respectively, an end view and a side view ofone of our brackets, having a base-piece, A, suited for attachment tothe side of a beam, being the same basepiece as we show in Fig. 32. Thenovelty consists in the means whereby we adjust the end B of theextension-piece in the split boss ]3 of the bracket-base. This iseffected by two screws, (marked K and K the former being screwed througha threaded hole made in the end of a carrier-piece, K, which is fixed tothe extreme end B of the extension-piece, at the mid-length whereof iscast a small projecting lug, (marked K through a threaded hole in whichthe screw K is placed. In whichever direction the extension-piece mayrequire to be turned to suit the position or line of the shaft the endsof the adjusting-screws can operate against the opposite ends of thesplit boss, and by slackening one screw and tightening up the other theround end B of the extension-piece is caused to slide in the split bossin the direction required. The shank of the plain bearing of thisbracket is shown to be adjusted by a tailscrew, as in our primaryarrangement; but any of the other means of adjustment herein shown maybe applied.

Figs. 42 and 43 exhibit, respectively, an end view and a side view of anelongated bracket base-piece, A, furnished witha split boss, B andadapted as a hanger to a beam. Occasionally we find the use of such abracket basepiece as this very desirable, as it may be combined withmost of the extension-pieces and slia-nked bearings heretoforedescribed. For adjustment the duplex screws, or the two screws K and Kmentioned in the last paragraph, would be found very suitable.

Fig. 44 exhibits a bracket-bearing similar to the last, but fixed to thesurface of a wall. The bearin g is coupled, but not lined, and is placedin a position to receive a horizontal shaft.

Fig. 45 represents a bracket-bearin g similar to that shown anddescribed with reference to Fig. 32, excepting that the sole-plate ofits hase-piece A is fixed to the top of a beam instead of to the side,and its extension-piece and hearing are fixed in a position to receive ahorizontal shaft instead of a vertical shaft, as shown by the figurereferred to.

Sheet 7;: Our object in supplementing our specification by the additionof this sheet of drawings is to show the general adaptability of ourcombination ln'acket-bearings and their capability of adjustmentaccording to the various positions in which they are, can, or may befixed for the purpose of carrying either hori zontal, diagonal, orvertical shat'tin g or shafts. For example:

Figs. 1, 2, and 3 represent three brackets constructed according to ourprimary arrange ment, as shown and described with reference to Figs. 1,2, and 3 on Sheet 1. These three brackets are all alike, and it will beseen are fixed in three different positions for the purpose of carryinghorizontal shafts, viz: Fig. l isemployed as a hanger bolted to anoverhead beam, Fig.2 is disposed in the position of a wall-bracket fixedto a pillar, and Fig. 3 is mounted as a pedestal-bearing and is boltedto a floor.

Figs. 4, 5, 6, and 7 exhibit a range of our bracket bearin constructedaccording to some of the modifications described, and shown on Sheet 2,and carrying a line of horizontal shaftin g under conditions where themeans of fixing the sole-plates of the brackets vary considerably. Thus,Fig. 4 is a similar bracket to that shown by Fig. 45 on Sheet 5,excepting that instead of the sole-plate of the bracketbase being shapedfor attachment to the top surface of a beam,'it is altered in form andmade concave for the purpose, as shown, of fixing it to the verticalsurface of an upright pillar. Fig. 5 is disposed as ahan gin g bracket,and in construction is like the modification shown by Fig. 43 on Sheet6. Fig. 6 is disposed in a wall-box, and is similar to Fig. 29

on Sheet 5. Fig. 7 is seen as ahanging bracket, being the same as themodification described with reference to Fig. 36 on Sheet 6, and whichis there shown as a wall-bracket.

Figs. 8, 9, and 10 represent three bracketbearin gsdisposed for carrying-a diagonal shaft, Fig.8 being a bracket similar to Fig. 12 on Sheet 2,excepting that the soleplate is made concave for attachment to a pillar.Fig. 9 shows a bracket of the same construction attached to a wall, forwhich purpose its soleplate is, as usual in such cases, made flat; and

Fig. 10 shows a bracket disposed as apcdes- .tal fixed to a floor. Thislast bracket is the same as the modification shown by Fig. 43,

which is seen on Sheet 5 disposed as a hanger attached to an overheadbeam.

Fig. 11 represents a bracket with its basepiece attached to the sideinstead of to the top of a beam, as is shown and described withreference to a similar bracket exhibited by Fig. 45 on Sheet 5, both ofthese brackets being arranged for carrying horizontal shafts.

Fig. 12 represents a bracket fixed to a wall and having itsextension-piece and bearin g arranged for carrying the upper end of avertical shaft; and Fig. 13 exhibits a bracket fixed as a pedestal upona tloor and having its hearing partly bored out and turned upward to actas a foot-step to receive and support in position the lower end of thevertical shaft mentioned in the last paragraph. This same bracket isshown fixed as a wall-bracket by Fi 26, Sheet 5, and is there arrangedfor carrying a horizontal shaft.

Having now fully described the nature, the object, and the advantagesderivable from the use of our invention, as shown and described withreference to the figures on Sheets 1, 2, and 3, and also to the severalmodifications shown and described with reference to the figures onSheets 4, 5, and 6, we wish it to be understood that we lay no claim tothe exclusive construction ofbrackets with adjustable plumber blocks orbearings, because we have for many years been accustomed to make and usesuch brackets and bearings and adjust them by means of wedges andslo'tted holes, and we have occasionally seen and used extension ordistancing pieces with such brackets when from necessity they have beenso placed that their bearings fell short of a line of shaft, orotherwise did not reach the position required. We also know that othercombination bracket-bearings have at times been introduced; but none ofsuch bracket-bearings that we have ever seen have the unlimited powerand freedom of adjustment, the adaptability to all conditions,positions, .and purposes, and (what is of the utmost importance) themeans after adjustment of inimovably and rigidly fixing the severalparts so completely in their adjusted positions relatively that suchposition is permanently maintained. Therefore,

What we claim as our invention consists as follows, viz:

1. The bracket base-pieces of the several forms herein described, andshown in the drawings hereto annexed, such base-pieces having severallya sole-plate and either a crampingeoupling, a split boss, or ahalf-bearing, respectively furnished with lugs for crampingbolts eitherstraight or staple formed, for the purpose of griping and rigidlyholding the adjustable ends of extension-pieces after their finaladjustment, in the manner and for the purposes herein described.

2. The bracketextension-pieces having each either of the several formsherein described, and shown in the annexed drawings, suchextension-pieces severally having one end suitably fashioned forentering or consorting with either the cramping-coupling, the splitboss, or the halt-bearing (as the case may be) of the bracketbase-piece, and carrying at the other or outer end either a split bosswith lugs and cramping-bolt, or a halt-bearin g with lugs and, a stapleformed cramping bolt or bolts, for the purpose of receiving and afteradjustment griping and rigidly holding permanently the shank of thebracket-bearing, all after the manner and for the purposes hereindescribed.

8. The shaft and other bearings, when such bearings are severallyfurnished with a long projecting shank, as herein described, and

shown in most of the figures on the drawings hereto annexed, the shankof such bearings being specially designed to enter the split boss or (asthe case may be) engage with the halfbearin g formed on the outer end ofthe extension-piece ot' the bracket with which it is combined, and afteradjustment, by screws or otherwise, to be griped and rigidly heldthereby by means of cramping-bolts, in the manner and for the purposesdescribed.

4. The cramping-eouplings and split bosses,

respectively furnished with lugs and one or more cram pin g-bolts, alsothe half-bearings and staple-formed bolts as a means of connectin g and,after-adjustment, permanently fixing together the principal parts ofourcombination braeket-bearing-via, the base-piece, the extension-piece,and the shanked bearing after the manner described with reference to theseveral figures shown on the drawings hereto annexed, and for thepurposes herein set forth.

5. The within-described modes of adjusting the extension-pieces of ourbrackets after being adapted and connected to their several base-pieces,and the shanks of our bearings after being adapted and connected to theouter end of extension-pieces by means of adj ustingscrews, eithersingle or duplex, and severally constructed and applied after the mannerand for the purposes herein described with reference to the figures onthe drawings hereto annexed.

6. The mode described, and shown by Figs. 12, 13, and 14 on Sheet 2, ofadapting a strapguide to the end of a bearing-viz., by means of anannular clipwhen such bearing. is cast with a long shank, for thepurposes herein set forth.
